The Night Affair (1958)

"Paris Before Dawn - The end of an interlude of love, lust and murder...running its course while the city sleeps. As if terrified by the light of day...it waits, only to return under cover of another night."

Plot Summary

Vallois, a vice inspector for the Paris police, takes special interest in the plight of drug-addicted Lucky (Najda Tiller), whom he considers to be more victim than criminal. Taking it upon himself to wean Lucky away from narcotics, Vallois also wins her love -- and, incidentally, smashes the dope ring responsible for her addiction.
